WATER-HEATER FOB GAS-EANGES.,

Specification of Letters Patent.

Patented Atrug, f3, 1914i.

Application filed September 2li, 1913. Serial No. 791,621.

To all whom t may concern.'

Be it known that l, RICHARD G. "WHITE- HEAD, a citizen of the United States, residing at Trenton, in the county of Mercer and State of New Jersey, have invented new and useful mprovements in Water-Heaters for Gas-Ranges, of which the following is a specification.

This invention relates to water heaters for gas ranges and the like, the object of the invention being to produce an effective and practical device for simultaneously heating water and distributing the heat throughout the top `of the stove, the said device being a separable part of the stove and forming an attachment thereto, where- 'by the said device may be easily applied to and used in connection with cooking stoves or ranges already in use and which use gas, hydrocarbon oil or other fuel in connection with suitable burners.

With the above and other objects in view, the -invention consists .in the construction', combination and arrangement of parts, as will hereinafter be more fully described, illustrated and claimed.

In the accompanying drawings: Figure 1 is a plan view of a gas range, showing the device of this invention in position thereon, one of the lids being removed to expose a burner. Fig. 2 is a vertical section on the line 2-2 of Fig. 1. Fig. 3 is a similar section on the line 3 3 of Fig. 1.

Referring to the drawings 1 designates the marginal portion or rim of the frame of a gas range, 2 designating the fuel supply pipe, 3 the supporting means therefor, 4f the branch pipes leading to the burners, one of which is shown at 5, and 6 the regulating cocks controlling the supply of fuel to the burners. All of the parts just referred to are of the usual construction and arrangement, the frame 1 being rabbeted as shown at 7 to receive the usual top section or grate which in the accompanying drawings has been removed or omitted, the water heater and heat distributer being shown in place thereof.

The device of this invention embodies a top plate 3, a bottom plate 9 and an intermediate plate 10. All of these plates extend horizontally in parallel relation to each other as shown in Figs. 2 and 3 and form the top and bottom walls of a lower water jacket or water heating compartment 11 and an upper heat distributing compartment or chamber 12. top and bottom and intermediate walls are formed with vertically alined openings to form stove holes directly over the burners 5 and corresponding in number with the number of burners with which the stove is equipped. Around each of the .stove holes, the bottom wall 9 and the intermediate wall 10 are connected or united by a vertically extending web 13 and said walls are further connected at their outer or marginal edges by a surrounding web 14, the walls and webs 9, 10, 13 and lil thus forming a water jacket to which water is led through an inlet 15 indicated as formed in the bottom wall 9 and from which the water is led off through an outlet 16 shown as formed in the top wall 8, the outlet 16 being surrounded by an annular web 17 which extends upwardly through the heat distributing chamber.

ln order to provide for deflecting and circulating the water throughout all portions of the chamber 11, a water deflecting web 18 is interposed between the walls 9 and l0 and in the preferred embodiment of the invention, said deflecting web 13 is provided with curved portions 19, concentric with the stove holes asindicated by dotted lines inFig. l. This causes the water to circulate around the stove holes, thereby obtaining a quicker heating of the water.

@n the top face of the intermediate wall 10 and adjacent to each stove hole is a circular series of upstanding ribs or grate bars 2O radiating from a common center and eX- tending outwardly to the edge of the lid receiving hole 21 in the top wall 8, said grate bars forming a support for one of the lids 22. ln addition to forming supports for the lids 22, the grate bars 20 also serve to materially stiifen and reinforce the entire structure and prevent the horizontal walls from sagging when subjected to excessive heating.

From the foregoing description, it will now be seen that the device of this invention is in the form of water heating and heat distributing attachments to gas ranges and the like, the outer margin of the structure being rabbeted as shown at 23 to adapt it to be seated in the correspondingly rabbeted marginal rim or frame of the stove as indicated in Figs. 2 and 3. The device comprises a lower water heating chamber or compartment with means for causing a At suitable points the saidr circulation of water throughout the same,

anda heat distributing chamber or compartmeiitV locatedv above said water heating chamber and coimectedtherewith 'byvertr cally extending webs and grate bars which form the supporting means orthe .detachable lids. One or more burners may be covered or uncovered by means of the lids so as to expose the desired number of burners.

ln order to provide for an auxiliary small burner such as is used for heating small utensils and keeping their contents heated,

the heating device of this invention may be provided, as shown in Figs. 1 and 8, with a relatively small hole 24: surrounded by a vertically extending annular wall or web 25 and covered by a lid 26 when the said auiril` iary burner (not shown) is not in use. It will be observed by reference to Fig. 3 that the web 25 which bounds the small lhole 2e is also surrounded by the water jacket or heating chamber and also by the upper heat distributing compartment.

it will of course be understood that the attachment hereinabove described may be made in any size and with any desired number lot stove holes to conform to and fit upon the frame of a stove or range having any number of burners and arranged as shown in Fig. l, or in tandem or placed under any other arrangement. These and other changes in the form proportion and minor details of construction may be resorted to without departing from the prin*I ciple or sacrilicing any of the advantages ot the invention.

What l claim is:

l. A stove top embodying a top wall, a bottom wall, an intermediate wall parallel to and located between the top and bottom walls, all of said walls being formed with vertically alined holes occurring above the stove burners, marginal webs connecting the bottom and intermediate walls around said holes and around the outer edges or rim of the stove top forming a water heating jacket having an inlet and an outlet, a marginal web connecting the outer edges of the top and intermediate walls and 'forming a heat distributing chamber, and lids for said holes.

2. A stove top embodying a top wall, a bottom wall, an intermediate wall parallel to and located between the top and bottom walls,.all of saidwalls beingl formed lwith vertically alined holes occurring above the stove burners, marginal webs connecting the holesyand around the outer edges or rim et the stove top forming a water heating jacket having an inlet and an outlet, a marginal `web connecting the outerl edges of the top and intermediate walls and forming a heat distributing chamber, lids' for said holes, and lid-supporting grate bars on the upper tace of said intermediate wall.

3. A stove top embodying a top wall, a'

bottom wall, an intermediatewall parallel to and located between the top and bottom walls, all of said walls being formed with vertically alined holes occurring above the Ybottom and intermediate walls around said stove burners, marginal webs connecting theU bottom and intermediate walls around said holes and around the outer edges or rim of the stove top forming a water heating jacket having an'inlet and an outlet, a marginal web connecting th'e outer edges ot the walls, all of said walls being formed with vertically alined holes, occurring above the stove burners, marginal webs connecting the bottom and intermediate walls aroundpsaid holes and around the outer edges or rim of the stove top forming awater heating jacket having an inlet and an outlet, a marginal web connecting the outer edges ofthe top and intermediate walls and lforming a heat distributing chamber, lids for said holes, and a water deliecting and circulating web uniting the bottom and intermediate walls vand having` portions thereof concentric to the stove holes.

In testimony whereof I affix my signature in presence of two witnesses.
